I just put on 15x8 ralley rims all the way around. BFG T/A's -- 275/60/15 in the rear and 235/60/15 in the front. All four rims have 4" BS. The rears clear by 1/8" or so and the fronts are fine. Good stance and they look good together. There is plenty of room on the inner side of the rears. With 4.5 or 5 BS you could get a 295 or larger in there... the lips are not rolled. Just FYI for those looking for a "combo"
